Dingell Plans to Propose Carbon Tax

Rep. John Dingell, D-Mich., said he plans to issue a proposal when Congress returns from recess that would impose stiff new taxes on gasoline and end the mortgage interest tax deduction on "McMansions," or homes greater than 3,000 square feet, as a way to discourage over-consumption of fuel.

Dingell, chairman of the House Energy and Commerce Committee, believes the proposals will help reduce carbon emissions by 60 percent to 80 percent by 2050, according to The Washington Post. But opponents like the National Association of Realtors are crying foul.
